This week, we show you how Syria's once-thriving second city of Aleppo has been largely reduced to ruins, this amid continued air strikes by the Syrian regime and its Russian ally. We also head to Yemen, where an air strike by the Saudi-led coalition has killed 140 people, escalating the conflict between the Riyadh-backed government and opposition Houthi rebels.

Finally, we listen to some Iranian rap: the bad boys of music, formerly known as Zedbazi, continue to dominate download charts in the Islamic Republic. Rapper Alireza JJ joins us on the show.
